LuNc'H-Box.

SPECIFICATION forming' part of Letters- Patent No. 279,662, dated June19, 1883.

Application filed November 20, 1882. (Model.)

To ZZ whom it nuty concern: Be it known that I, JOHN R. OLINGER, `oChicago, in the county of Cook and State of Illinoishave inventedcertain new-and useful Improvements in Lunch-Boxes, of which thefollowing, in connection with the accompanying drawings, is aspecification.

In the drawings, Figure lis a perspective representation of a lunch-boxembodying my invention, showing the same unfolded or ready Fig. '2 is aperspective view of the frame. Fig. 3 is a like representation of thesame when folded. Fig. 4 is a Vertical central longitudinal section ofthe folded box. Fig. 5 is a' central` cross-section in the line m .r ofFig. 1; and Figs. 6, 7, and 8 are. like sectious, showing the change inthe position of the several parts during the operation of folding orclosing the box; and Fig. 9 i

is a Vertical longitudinal central section of the parts as shown in Fig.7, but upon a some-, what smaller scale;

Like letters of reference indicate like parts.

There are several principal parts forming this box-the lid A, the wireframe B, the sides O and D, the ends E and F, the bottom G, Vand thelinked piece H. The lid A, the sides C and D, and the ends E and F areall hingcd to the frame B, the sides and ends depending therefrom whenthe box'is open or ready to receive its contents, and the lid beinghingedthereto at one end, so that it may be 'folded over or laid uponthe upper edges of ranged Vertically, there'by preventing the side.

- pieces from being swung outwardly after they have been brought to averti cal position. The bottom G is hingcd to the lower edge of the'side piece D, and its opposite edge is turned upward and then downwardslightly, as shown at b, and the lower edge of the side piece C isturned inward and upward, as shown at c, to receive the depending tongueor lip on the free edge of the bottom piece, G, thus preventing' thepart G from being swung down below a horizontal position or below thelowea' edges of the sides and ends of the box when the box is opened foruse. `'In length and width the bottom piece, G, is such that it will beinclosed between the sides and ends of the open box.

The piece H is hingcd at its outer ends to the lower edges of the ends Eand F, and is jointed at its center, as shown at (1,01' iu any suitable'way It wi]] be observed that the piece H is `not so wide as the bottompiece, G.

I is a small catch to prevent the bottom piece, G, and the side piece towhich it is hingcd from being swung up too far when the box is beinglfolded' np, as will hereinafter more fully appear' Any suitable catchdevice may be employed for retaining the cover temporaril y in itsclosed position and looking the parts together temporarily when folded;or such a catch device may be omitted altogeth er without m ateriallyaffecting the principal objects of my invention. I will now proceed,however, to describe the catch device which I have-shown. I

K is a rectangularly-bent strip of sheet metal, hingcd to that end ofthe frame B opposite that to which the cover 01' lid A is hingcd, and eis a slot in the part K. i

L is a small tubular piece applied to the free end of the lid A, andarranged to enter the slot e when the piece K is turned up over thecover, as shown in Fig. 1. The cover will thus be held closed withsufticient certainty under ordinary V('.ircnmstances5 but to lock thecover in its closed position I hi nge to the part K the bentwire K',adapted to slide back .and forth laterally in the part K, and so formed'thatone'arm of the said wire will then move in and out of theeylindrical piece L, thus locking the cover in its closed position whilethe wire K' is in the said tube or cylinder.

M is a hooklshaped piece hingcd to thewire K', and the purpose of thishook will be hereinafter explained. N is a handle.

In order to fol d this box in the compact manner representcd in Figs. 2and3, I unlock the lid or cover A and throw it back, and then push upthe bottom piece, G, as indicated in ICO
